Pain palliation resulting from antitumor therapy provides direct evidence of treatment benefit when combined with evidence of antitumor activity. The US Food and Drug Administration (FDA) previously issued guidance regarding the use of patient-reported outcome (PRO) measures to support labeling claims. The purpose of this article is to identify common challenges and key design strategies when measuring pain palliation in antitumor therapy clinical trials that are consistent with PRO Guidance principles. ⋯ Improvement in cancer-related pain resulting from antitumor therapy is an important treatment benefit that can support drug approval and labeling claims when adequately measured if study results demonstrate statistically and clinically significant findings. Sponsors are encouraged to discuss pain palliation assessment methods with the FDA early in and throughout product development.

Randomized Controlled Trial
Patient-reported outcomes from EMILIA, a randomized phase 3 study of trastuzumab emtansine (T-DM1) versus capecitabine and lapatinib in human epidermal growth factor receptor 2-positive locally advanced or metastatic breast cancer.
This report describes the results of an analysis of patient-reported outcomes from EMILIA (TDM4370g/BO21977), a randomized phase 3 study of the antibody-drug conjugate trastuzumab emtansine (T-DM1) versus capecitabine and lapatinib in human epidermal growth factor receptor 2 (HER2)-positive locally advanced or metastatic breast cancer. ⋯ Together with the EMILIA primary data, these results support the concept that T-DM1 has greater efficacy and tolerability than capecitabine plus lapatinib, which may translate into improvements in health-related quality of life.

Dabrafenib has activity in patients with brain metastases, but little is known of the relative efficacy of treatment within and outside the brain. This study sought to examine the intracranial (IC) and extracranial (EC) patterns of response and progression in patients with active melanoma brain metastases treated with dabrafenib. ⋯ IC and EC melanoma metastases respond similarly to dabrafenib. There is no dominant site or pattern of disease progression in patients with brain metastases treated with dabrafenib. Salvage local therapy is possible in most patients after IC disease progression, with ongoing dabrafenib treatment possible in a subset of patients.

Multicenter Study
Prevalence and characteristics of moderate to severe fatigue: a multicenter study in cancer patients and survivors.
The effective management of fatigue in patients with cancer requires a clear delineation of what constitutes nontrivial fatigue. The authors defined numeric cutpoints for fatigue severity based on functional interference and described the prevalence and characteristics of fatigue in patients with cancer and survivors. ⋯ The current study statistically defined fatigue severity categories related to significantly increased symptom interference. The high prevalence of moderate=severe fatigue in both actively treated patients with cancer and survivors warrants the promoting of the routine assessment and management of patient-reported fatigue.

Individuals with schizophrenia are a vulnerable population that has been relatively neglected in health disparities research. Despite having an equivalent risk of developing most cancers, patients with schizophrenia are more likely to die of cancer than the general population. Cancer care disparities are likely the result of patient-, provider-, and systems-level factors and influenced by the pervasive stigma of mental illness. ⋯ Using a case, the authors illustrate clinical challenges for this population including communication, informed consent, and risk of suicide, and provide suggestions for care. Finally, recommendations for research to address the disparities in cancer care for individuals with schizophrenia are discussed. Despite significant challenges, with collaboration between oncology and mental health teams, individuals with schizophrenia can receive high-quality cancer care.
